SOFTENING YARNS AFTER DYEING.

SPECIFICATION forming part of Letters Patent No. 255,833, dated April 4, 1882.

' Application filed February 4, 1882. (No model.)

To allwhom it may concern Be it known that I, JosEPn BALSTER, of Ohemnitz, in the Kingdom of Saxony and Empire of Germany, have'invented certain new and useful Improvements in Softening Yarns,

' fore; and the invention consists ofanimproved process in which the banks of yarn are exposed to the action of longitndinally-reciprocating and simultaueously-revolving frictionsurfaces, and in which the dust is removed by frequently stretching theyarns during the operation.

The invention consists, secondly, of an improved apparatus having grooved rollers which are reciprocated longitudinally, or in the direction oftheir axes, and revolved simultaneously by transmitting mechanism to be more fully described hereinafter. The banks are passed through between the rubbing-rollers, and are stretched from time to time by drawing back a lever which carries the spool upon which the hanks are placed.

In the accompanying drawings, to which reference is made, Figure 1 is an end elevation of the apparatus. Fig. 2 is a plan; Fig. 3, a side view. Fig. 4 shows the upper frame or standards of the apparatus, with the rollers removed, in section on line AB, Fig. 3. Fig. 5 is a rear view of the upper frame or standards, and Figs. 6 and 7 show a modified arrangement of the mechanism for effecting the longitudinallyprojectin g movement of the rollers.

Similar letters of reference indicate corresponding parts.

a is a frame which carries at its upper part the standards I) b. The standards b I) support in suitable bearings the shafts c and d, which are arranged parallel to and vertically above each other. One of the shafts is rotated by a crank-handle, or bya belt and pulley, or by other suitable means. These shafts carry at their outer ends the rollers e andf, which are either grooved or smooth, and in the latter case they are by preference covered with coarsely-grained india-rubber.

On one or both ofthe shafts cand darefixed the wave-wheels g 9 the edges of which are bent or corrugated, as shown, and arranged to take into the notches h 7L2, formed in fixed lugs h of one of the standards I) b. The wavewheels 9 9 effect during each revolution several backward and forward movements or reciprocations of the rollersin opposite directions to each other, but in the direction of their axes.

. The top bearin g, m, of the standard badjoining the upper roller is connected with a lever, 'i, by means of a coupling-rod, z 2, as shown in Figs. 3and 4, the leveri being provided with an adjustable weight, k, whereby the roller f is pressed against the roller 0.

In order to allow of the upward and downward movement of the rollerf, and for the purpose of accurate adjustment, the bearings l of a n ofstandards, as shown in Figs. 3, 4, 5, 6, and 7.

In Figs. 6 and 7 is shown a modification of the mechanism for longitudinally moving or reciprocating the rollers, which arrangement is specially, applied to, rollers which are not grooved. In this arrangement only one shaft is furnished with the wave-wheel g, and the longitudinally-reciprocating motion of this shaft is double-forked lever 0, which engages grooved rollers on the shafts c and d, so that the rollers must always move in longitudinal but opposite directions to each other, even if they do not revolve at the same speed-an arrangement which can easily be made in the case ofsmooth' rollers.

The banks of yarn to be treated. are placed on the spool r, furnished with disk-shaped heads and carried by a fixed pin, g, at the upper end of a lever, 19. The hanks are also passed over the conical projecting part c of the lower roller, e, as shown in Fig. 3, and the rollers are then caused to be rotated. The

the second standard,b, are free to turn on a pin carried by the adjustable slotted side plates,

transmitted to the upper shaft by means of the a yarn follows the rotation of the rollers, is seized by the grooves ofthe same, and is rubbed so as to become pliable and soft by the longitudinally-reciprocating motion of the rollers. From time to time the banks are tightly stretched while they are being operated upon the rollers by quickly drawing back the lever 19, which carries the spool r, as shown in dotted lines in Fig. 1, whereby the dust ofthe dye worked off the yarn by the rubbing of the rollers is removed therefrom.

Havingthus described my invention, I claim as new and desireto secure by Letters Patent- 1. The process herein described for softening hard yarn, which process consists in passing theyarn between rubbing-surfaces to which simultaneously longitudinally reciprocating and rotating motion isimparted,andremoving the dust from the yarn by quickly stretching the banks while they are operated upon'by the rubbing-surfaces, substantially as set forth.

2. The combination of the revolving rollers of, supporting-standards b b, carrying the shafts c d, the bearing ofthe upper shaft, (7, be-

ing pivoted to the outer standard, means for longitudinally reciprocating the rollers, and a weighted lever connected to the bearing ofthe upper shaft on the standard adjoining therollers, whereby the upper roller is pressed down upon the lower roller, substantially as specified.

3. The combination of the revolving andlongitudinally-reciprocating rollers e f with a pivoted stretching-lever, 10, carrying the spool r for the hanks, substantially as set forth.

4. The combination of the revolving and 1011- gitudlnally-reciprocating rollers e f, the lower of which has aconical extension, 0, while the upper one is weighted, with a pivoted stretching-lever, 9, carrying the guide-spool r for the hanks, substantially as specified.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 1st day of November, 1881.
